We try to solve very complicated problems without letting people know how complicated the problem was.

With the early prototypes, I held the phone to my ear and my ear [would] dial the number. You have to detect all sorts of ear-shapes and chin shapes, skin colour and hairdo... that was one of just many examples where we really thought, perhaps this isn’t going to work.

In our quest to quickly make three-dimensional objects, we can miss out on the experience of making something that helps give us our first understandings of form and material, of the way a material behaves--'I press too hard here, and it breaks here' and so on. Some of the digital rendering tools are impressive, but it's important that people still really try and figure out a way of gaining direct experience with the materials.

There are 9 rejected ideas for every idea that works.

There are a thousand no's for every yes.

But one of the things that really irritates me in products is when I'm aware of designers wagging their tails in my face.

We are really pleased with our revenues but our goal isn't to make money. It sounds a little flippant, but it's the truth. Our goal and what makes us excited is to make great products. If we are successful people will like them and if we are operationally competent, we will make money.
